Hello, I saw a lot of tutorials about setting postfix with dovecot sasl but I would like more.
I want to set a SSO system with roundcube on dovecot. I would like to know how to make dovecot work with sasl or saml, not as a provider but as a service plugging on an external provider. I saw there is an EXTERNAL auth mechanism but I didn't find any doc about it. Can you help me ? Thanks.
